Cam card says 6329 on the lobe, both intake and exhaust - High RPM II Solid
Proof once again that one should never rely on memory!!
Okay....... so you’re not so far off then.
Those lobes should be fine with the 1.7......... still need adequate load though.
I’d have the current springs tested to make sure they haven’t lost too much.
If they’re still good, set them up at 150-155 on the seat....... and that will give you a little more closed/open load, along with putting them closer to c/b(which I would expect to be enough of a change to calm things down).
I’ve run a cam with that lobe family in a 446 with RPM heads on the dyno, using the single springs that came on the heads to 6500 and saw no signs of float to that point. That motor had HS 1.5 rockers (that measured 1.55).
Did you have a different cam in that motor at one point that had an XX intake lobe?
